I have decided to write down my hypothesis of the post big bang. My hypothesis states that there was a universe prior to this universe but was destroyed. The destruction was caused by the big crunch and the sub atomic particles formed together to cause a big bang. This is rather a easy way to describe it but I will become more descriptive of my hypothesis.
The beginning, Space is infinite while the universe is created by the big bang. The energy was there as it is in a isolated system. It remains constant but cannot be created. This the conservation of energy. The Big Bang explains how the universe expanded into it’s present state. When the universe’s expansion reverses and the universe collapses. It will end in a black hole singularity.
Quantum theory says that "virtual pairs" of particles sometimes wink into existence from the fabric of space itself. These particles quickly cancel each other out and vanish. But if a pair of particles appear just outside a black hole's horizon, one may fall inside, never to make it outside again. If the one on the outside doesn't fall through the horizon, then the particles can't cancel each other out. In essence, that "steals" a little bit of mass from a black hole. Over countless billions of billions of billions of years, the mass loss could become substantial enough to cause the black hole to vaporize. Material would come out, but not in its original form -- only as energy and subatomic particles. The Quantum theory described by Stephen Hawkings.
These subatomic particles would cause rapid expansion which would be the big bang. How many universes prior to this are unknown, it could be infinite which would be the reason I proposed it as infinite universes.
